Universal non stationary dynamics at the depinning transition
Alejandro B. Kolton, Gregory Schehr, Pierre Le Doussal
We study the non-stationary dynamics of an elastic interface in a disordered medium at the depinning transition. We compute the two-time response and correlation functions, found t…
Dynamic crossover in the global persistence at criticality
Raja Paul, Andrea Gambassi, Gregory Schehr
We investigate the global persistence properties of critical systems relaxing from an initial state with non-vanishing value of the order parameter (e.g., the magnetization in the…
Disordered free fermions and the Cardy Ostlund fixed line at low temperature
Pierre Le Doussal, Gregory Schehr
Using functional RG, we reexamine the glass phase of the 2D random-field Sine Gordon model. It is described by a line of fixed points (FP) with a super-roughening amplitude $\bar{(…
Non-equilibrium critical dynamics in disordered ferromagnets
G. Schehr, R. Paul
We discuss some aspects of the non-equilibrium relaxational dynamics which occur after a quench at a disordered critical point. In particular, we focus on the violation of the fluc…
Strong Randomness Fixed Point in the Dissipative Random Transverse Field Ising Model
Gregory Schehr, Heiko Rieger
The interplay between disorder, quantum fluctuations and dissipation is studied in the random transverse Ising chain coupled to a dissipative Ohmic bath with a real space renormali…
Functional Renormalization for pinned elastic systems away from their steady states
Gregory Schehr, Pierre Le Doussal
Using one loop functional RG we study two problems of pinned elastic systems away from their equilibrium or steady states. The critical regime of the depinning transition is invest…
